There's a good explanation of the different SIM sizes on the 4G (independent) website here
If your micro-SIM has perforations, you may be able to cut it down to a nano-size, otherwise you can order a replacement SIM here . A new EE SIM comes with perforations that you can use to cut down to whichever size you need.
@NERAKION@bristolian You don’t need to cut the sim you should be able to push out the part you need if it was a 3 in 1 sim. EE have been using 3 in 1 sim for a long time now so it’s very lightly it is.
To contact EE Customer Services dial 150 From your EE mobile or 0800 956 6000 from any other phone.
